Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a depth counter with an anti-skid wire free opening and closing pressure structure. Background Technology

[0002] Ultrasonic testing is one of the main methods for detecting defects in pile foundations. After the pile hole is formed but before concrete is poured, several acoustic logging tubes are pre-embedded in the pile as channels for sound wave transmission and reception transducers. Testing begins several days after the concrete is poured. An acoustic wave detector is used to measure the acoustic parameters of the sound waves passing through each cross-section of the pile at certain intervals along the longitudinal axis of the pile. These test data are then processed, analyzed, and judged to determine the location, extent, and degree of defects in the pile concrete, thereby inferring the continuity, integrity, and uniformity of the pile concrete and assessing the pile integrity level. During the entire measurement process, the acoustic logging tubes are first filled with clean water. The acoustic probe must be lowered synchronously, and the depth data of the probe's descent must be recorded simultaneously. Therefore, an auxiliary device is needed to simultaneously lower the cable and record the data. During the probe lowering process, cable slippage and skipping must be avoided to prevent inaccurate counting and cable jamming.

[0003] Currently, most acoustic wave meter counters suffer from cable slippage and jumper issues. During the lowering and retrieval of the probe, if the cables become tangled, jumpers or even jamming may occur. Once the cables become tangled, the detection task needs to be stopped to tidy them up. Therefore, a reliable cable splitting and clamping structure needs to be designed. Summary of the Invention

The second side cover is connected to the other side plate of the mounting frame through a locking assembly.

[0014] Furthermore, the locking assembly includes a push switch and a buckle connected to the push switch. The push switch passes through the second side cover and is provided with a push spring between it and the outer side of the second side cover. The buckle is provided on the inner side of the second side cover. The end of the push switch is also provided with a locking nut for limiting the buckle.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-4As shown, a depth counter with a free-opening and closing anti-skid wire pressing structure includes a mounting frame 1 and a counting wheel 20 disposed within the mounting frame 1. The counting wheel is provided with a plurality of counting wire grooves 21. An electrical control box 2 is provided on one side of the mounting frame 1. An openable and closable pressure cover 3 is provided on the upper part of the mounting frame 1. At least one set of pressing mechanisms 4 is provided on the inner side of the pressure cover 3. The pressing mechanism 4 is provided with a plurality of pressing wheels corresponding one-to-one with the counting wire grooves 21. A rotatable and adjustable rocker arm seat 5 is also provided on the inner side of the pressure cover 3 near the pressing mechanism 4. The rocker arm seat 5 is provided with a plurality of wire dividing rocker arms 6. The area between adjacent wire dividing rocker arms 6 corresponds to one of the counting wire grooves 21.

[0031] This depth counter with its anti-jump cable free-opening and closing pressure structure can effectively separate cables that need to enter or exit the counting cable slot 21 by setting the cable separating lever 6, avoiding jumper or jamming problems caused by cable tangling. It eliminates the need to stop the detection task to tidy up the cables, improving the efficiency and convenience of the depth counter. Moreover, the whole structure is simple and easy to install and use.

[0032] The wire pressing mechanism 4 uses its pressing roller to cooperate with the counting wire slot, which can conveniently introduce (recycle) the cable and also lead out (release) the cable. Each set of wire pressing mechanisms 4 is provided with several wire separating rods 6 on the side, so that the cable on each counting wire slot 4 is separated by the wire separating rods when entering and exiting, and the cable can be retracted and released relatively independently. This can avoid the cable from getting tangled and jumping out of the slot, which is conducive to the orderly retraction and release of the cable, thereby improving the counting efficiency and counting accuracy.

[0033] The swing arm seat 5 is rotatable relative to the pressure cover 3. By rotating the swing arm seat 5, the dividing swing arm 6 can be placed at different angle positions. The range of rotation of the swing arm seat 5 is 0-90°.

[0034] Furthermore, the pressure mechanism 4 includes a connecting shaft 401 connected to the inner side of the pressure cover 3. A plurality of pressure rollers are spaced apart on the connecting shaft 401. The pressure rollers are bearings 402. A spacing retaining sleeve 403 is also provided on the connecting shaft 401 between adjacent bearings 402. The spacing retaining sleeve 403 is also provided between the bearings 402 and the side wall of the pressure cover.

[0035] The wire pressing mechanism with this structure is relatively simple and easy to install and disassemble. The bearing 402 can rotate on the connecting shaft 401 to allow the cable to pass through, and using the bearing 402 as a pressure roller facilitates installation and replacement. The spacing maintaining sleeve 403 can maintain the spacing between adjacent bearings 402. The counting wheel is also equipped with a sensor, which is connected to the control board in the electrical control box, and can count the passing cables to calculate the length of cable reeling in and unreeling.

[0036] Furthermore, the pressing mechanism 4 consists of two sets arranged in the front-to-back direction, one for inlet and one for outlet; correspondingly, two swing arm seats 5 are also provided.

[0037] Furthermore, in combination Figure 5 As shown, the rocker arm seat 5 is connected to the inner side of the pressure cover 3 via the rocker arm shaft 9. The rocker arm seat 5 is provided with several connecting holes, and one end of the branching rocker arm 6 is screwed into the connecting hole. The pressure cover 3 is also provided with a limiting component, which acts on the rocker arm seat 5 to make the branching rocker arm 6 suspend in a vertical or horizontal position.

[0038] The dividing line swing arm 6 can be easily connected via a threaded connection, or other methods can be used. The limiting component can limit the extreme positions of the swing arm seat 5, allowing the dividing line swing arm to stop at its extreme positions, such as horizontal and vertical positions.

[0039] Furthermore, the limiting component includes a plurality of short screws 10 disposed within the top cover 301 of the pressure cover 3. One end of each short screw 10 is connected to a top block 12 via a spring 11. One end of the top block 12 extends out of the top cover 301 and abuts against the rocker arm seat 5. The limiting component also includes a limiting block 13 disposed inside the pressure cover 3, and a limiting groove 14 disposed on the rocker arm seat 5 that cooperates with the limiting block 13.

[0040] During rotation, the rocker arm seat 5 presses against the top block 12. Due to the spring force at the other end of the top block 12, it gradually presses against the rocker arm seat 5. When the dividing rocker arm 6 is in a vertical position, perpendicular to the top of the pressure cap, the top block 12 can hold the rocker arm seat 5 in place. Simultaneously, the limiting groove 14 engages with the limiting block 13, keeping the dividing rocker arm vertical. When the dividing rocker arm 6 is adjusted from a vertical to a horizontal position, the pressing force of the top block changes under the spring force, decreasing and then increasing again. When the dividing rocker arm is horizontal, it can again press against the rocker arm seat, and the rocker arm seat 5 will not continue to rotate under the limiting position of the pressure cap 3.

[0041] Furthermore, the pressure cap 3 includes a top cover 301, and a first side cover 302 and a second side cover 303 disposed on both sides of the top cover 301. The pressure wire mechanism 4 and the swing arm seat 5 are respectively installed between the first side cover 302 and the second side cover 303. The first side cover 302 is placed on the side plate of the mounting frame 1 and is rotatably connected to the side plate of the mounting frame 1. The second side cover 303 is connected to the other side plate of the mounting frame 1 through the locking assembly 7.

[0042] The pressure cap 3 with this structure is easy to install on the mounting frame 1. One side of the pressure cap can be opened and closed to flip up or press down the pressure cap 3. The connecting shaft 401 and the swing arm shaft 9 can be installed in parallel between the first side cover 302 and the second side cover 303.

[0043] Furthermore, in combination Figures 6-9 As shown, the locking assembly 7 includes a push switch 701 and a buckle 702 connected to the push switch 701. The push switch 701 passes through the second side cover 303 and a push spring 703 is provided between it and the outer side of the second side cover 303. The buckle 702 is provided on the inner side of the second side cover 303. The end of the push switch 701 is also provided with a locking nut 704 for limiting the buckle 702.

[0044] With this configuration, the latch 702 can connect to the latch position on the mounting frame 1 to close the pressure cover. When the pressure cover 3 is closed from top to bottom, the latch 702 can automatically lock. When the push switch 701 is pressed, the latch 702 can deflect, causing the end of the latch 702 to disengage from the latch position, thus unlocking the pressure cover 3. The push spring 703 allows the push switch to reset automatically. The locking nut 704 can limit the latch, preventing it from disengaging from the push switch.

[0045] Furthermore, the inner side of the top cover 301 near the second side cover 303 is provided with a buckle limiting groove 15, and the inner side of the mounting frame 1 is provided with a locking groove 16; the buckle 702 is provided with a clearance groove 17 at the connection between it and the push switch 701, one end of the buckle 702 is an arc surface structure 19 and is arranged in the buckle limiting groove 15, and the other end of the buckle 702 is provided with a hook 18, which acts on the locking groove 16.

[0046] The upper end of the buckle 702 is curved, and it can slide within the buckle limiting groove 15 when pressed, so that the hook 18 below can disengage from the locking groove 16 (that is, the buckle position); the push switch 701 has a stepped cylindrical structure, and the buckle 702 is sleeved on the push switch. The clearance groove 17 provides room for the buckle 702 to rotate relative to the push switch 701.

[0047] Furthermore, the mounting frame 1 includes a mounting base plate 101 and a pair of side plates 102 disposed on the mounting base plate 101. The electrical control box 2 is mounted on the outer side of the side plates 102. The mounting base plate 101 is also provided with wire-blocking rods 8 at its two corners. The wire-blocking rods 8 are rotatable on the mounting base plate 101, and the cable moves in the area between the pair of wire-blocking rods 8.

[0048] One way to use the depth counter of this anti-skid cable free-opening and closing clamping mechanism is as follows: Before use, both sides of the cable distribution levers can be horizontally oriented. Since the cable distribution levers are held in place by the movable top block, they can stop at two extreme positions within a 90-degree range of motion. The top block then holds them in place. The movable top block, under the force of the compression spring, effectively presses against the lever seat, allowing the lever seat to move freely while remaining in one of its two extreme positions. After placing the cable into the cable slot, close the cover. The latch automatically engages when the cover is closed. Then, lower the cable distribution levers, distributing the cable between the corresponding levers. This helps to separate any tangled cables in advance, preventing them from getting stuck in the counting slot and causing a jump. During cable feeding, the rear cable distribution levers can separate the cables fed into the counting slot, preventing them from tangling together and entering the slot. During cable retraction, the front cable distribution levers can also perform the same cable separation function. When the cable reeling is complete and the cable needs to be removed, first adjust the front and rear cable reeling levers to the horizontal position, then press the push switch. The cover can be easily opened, and the cable can be removed. Then lower the front and rear cable reeling levers and close the cover.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
